Supervisors Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to ensure correct voltage thresholds and package variants. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to ordering. Check for any lead time variations associated with the S-19109 series production schedules. Ensure the selected part number matches the required operating temperature range and output configuration for your specific design constraints.

Supervisors Selection Notes

Select this component when a fixed 1.8 V detection threshold is required with minimal quiescent current. The open-drain output necessitates an external pull-up resistor for proper logic level interfacing. Consider the S-19109 series if higher accuracy or different voltage options are needed. Evaluate the SOT-23-5 footprint compatibility during PCB layout. Compare against other S-1000 series parts if alternative thresholds or output types are preferred.
